Preheat the oven to 450F.

Place the beans on a baking sheet and drizzle with grapeseed oil. Toss to coat and then spread into a single layer. Roast until soft and gorgeously caramelized, 12-15 minutes. Toss them once or twice so they cook evenly.

While beans are roasting, in a large bowl, add soy sauce, lemon juice, sesame oil and chili garlic sauce (if using). Stir to combine.

When the beans are done, add them to the sauce and toss to coat. Sprinkle with sesame seeds and serve. These are also great at room temperature.
